mkArgDescr :: DynFlags -> [Id] -> ArgDescr Source

emitCall :: (Convention, Convention) -> CmmExpr -> [CmmExpr] -> FCode ReturnKind Source

emitCall conv fun args makes a call to the entry-code of fun, using the call/return convention conv, passing args, and returning the results to the current sequel.

emitReturn :: [CmmExpr] -> FCode ReturnKind Source

Return multiple values to the sequel

If the sequel is Return

    return (x,y)

If the sequel is AssignTo [p,q]

   p=x; q=y;

adjustHpBackwards :: FCode () Source

emitClosureProcAndInfoTable :: Bool -> Id -> LambdaFormInfo -> CmmInfoTable -> [NonVoid Id] -> ((Int, LocalReg, [LocalReg]) -> FCode ()) -> FCode () Source

emitClosureAndInfoTable :: CmmInfoTable -> Convention -> [LocalReg] -> FCode () -> FCode () Source

slowCall :: CmmExpr -> [StgArg] -> FCode ReturnKind Source

directCall :: Convention -> CLabel -> RepArity -> [StgArg] -> FCode ReturnKind Source

mkVirtHeapOffsets :: DynFlags -> Bool -> [(PrimRep, a)] -> (WordOff, WordOff, [(NonVoid a, ByteOff)]) Source

mkVirtConstrOffsets :: DynFlags -> [(PrimRep, a)] -> (WordOff, WordOff, [(NonVoid a, ByteOff)]) Source

Just like mkVirtHeapOffsets, but for constructors

getHpRelOffset :: VirtualHpOffset -> FCode CmmExpr Source
